Scientists Synthesize a New Form of Silicon

Using a novel high-pressure precursor process, scientists from the Carnegie Institution for Science have synthesized an entirely new form of silicon. Washington, D.C. — Silicon is the second most-abundant element in the earth’s crust. When purified, it takes on a diamond structure, which is essential to modern electronic devices—carbon is to biology as silicon is […]

Special Coating Makes Batteries Safer

A new special coating developed by a team of researchers prevents electrical current from damaging the digestive tract after accidental battery ingestion. Every year, nearly 4,000 children go to emergency rooms after swallowing button batteries — the flat, round batteries that power toys, hearing aids, calculators, and many other devices. Ingesting these batteries has severe […]

New Research Shows Solid Nanoparticles Can Deform Like a Liquid

Using a combination of laboratory analysis and computer modeling, new research shows that nanoparticles keep their internal crystal structure while deforming like a liquid. A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal […]

Crumpled Graphene Forms Stretchable Supercapacitors

New research from engineers at MIT details how two-dimensional carbon “paper” can form stretchable supercapacitors to power flexible electronic devices. When someone crumples a sheet of paper, that usually means it’s about to be thrown away. But researchers have now found that crumpling a piece of graphene “paper” — a material formed by bonding together […]
